The bearings are specially designed to fit new or installed turbines, which are prone to electrical arcing from the passage of electric currents. Such arcing can result in surface damage to bearing raceways, excessive noise and premature lubricant aging leading to potential bearing failure, generator breakdown and unplanned turbine downtime.

The extra-large bore sizes range from 100 millimeters to 160 millimeters, and can be engineered with seals and shields or otherwise customized through the MRC made-to-order warranted products program.
